An ICD is a small, battery-powered device that continuously monitors your heart rhythm. If it detects a dangerously fast or irregular heartbeat, it can deliver a small electrical impulse—or a stronger shock if needed—to restore a normal rhythm.
ICDs are used to treat sudden cardiac arrest in people who are at high risk for ventricular tachycardia or ventricular fibrillation due to a weakened heart muscle, scar from a previous heart attack or specific conditions which put you at risk of dangerous electrical abnormalities. There are several types of ICDs, including traditional devices with leads inside the heart and newer subcutaneous ICDs that sit under the skin with a lead outside the heart.
You will need to take it easy for the first couple of weeks:
After that, you will have regular check-ups either in person or through our remote monitoring service to ensure the ICD is functioning well.
Your cardiologist will make a small incision and create a pocket under the skin to place the ICD. One or more leads (thin wires) will be guided through a vein into your heart using X-ray imaging. Once the leads are in place, the ICD will be connected and tested to ensure it is working properly. The incision will then be closed with dissolving stitches.
Let all your healthcare providers know you have a defibrillator—especially before having an MRI or surgery.
